1. Canada totals in the provincial and territorial gross domestic product by income and by expenditure accounts (PTEA) do not correspond to the national gross domestic product by income and by expenditure accounts (IEA) estimates at certain times of the year. The IEA's annual revisions, released each spring, result in a discrepancy between the estimates. The PTEA are brought back in line when the IEA's annual revisions are incorporated.Source: Statistics Canada, CANSIM, table 384-0038. Last modified: 2017-04-04.
